What, are "witness bastards", another species or something? Aren't they basically you with a little less information? I'd say when you left you burnt all your bridges. If you fling doctrine or information or words at them now like an AK-47 barrage, all you are going to do is make them dig deeper in to their fox holes.
Dawg, I agree with Gnat on this one.
No disrespect and many of us fully understand your frustration but this approach doesn't work. All your family is guilty of is the same things most religous people are guilty of, believing they are right. Catholics, Mormons, Muslims, Buddists and Hindus etc. wouldn't respond favorable to in their face discussions even if your intentions are to get them out, get them back and wake them up.
As was mentioned, live your life well, bring up information when appropiate to circumstances and stay calm. Know your facts and present them regardless of how they are recieved.
Not to hijack your thread, Why do many hear feel the need for name calling when it comes to the witnesses, namely " Witless, Kingdumb hall, Jehoover and the like. Frankly, we are better than this and outside of a few laughs for the cleverness of it, what good comes from it? Please don't call it therapy.I'm sure we get a fair amount of JW's looking at this site and I bet many are turned off by these terms used to describe their beliefs. I know at one time I would have and I'm sure we would like to help not turn off those parousing this discussion forum. Just my two cents.. Honest time, I was guilty of this early on and decided to stop doing it.
Good luck Dawg with your continued discussions with your family!
John
